General Discussion

As a biologist, I hear men ever so confidently talk about planting a seed. Sperm are not a seed! This is total crap. Sperm do not implant and grow, ever!! These idiots actually believe this is what happens. Reproductive biology education is desperately needed in school curriculum. It is different than Sex Ed.

An ovum can and does develop into a living creature in some species. Research has been done on the possibility of parthenogenesis in humans. The resulting offspring are all females, for now. This cannot be done with a sperm.


Up until fairly recently, the science of biology has been male driven. The female ovum always given a back seat to the manly sperm. Oh, he gushes, (no pun intended) about the millions of his sperm produced every day. It takes so much less to produce sperm than an ovum.

The Egg and the Sperm: How Science Has Constructed a Romance Based on Stereotypical Male-Female Roles” by Emily Martin is a logic and science driven paper that should be read.

There is ample evidence to show that as millions of human sperm cells swim towards a waiting ovum or egg, only one gets to fertilize it. Now, a new study shows that even though the fastest and most capable sperms reach the ovum first, it is the egg that has the final say on which sperm fertilizes it. This study is titled, "Chemical signals from eggs facilitate cryptic female choice in humans."

This new study by researchers from the U.K. and Sweden, looked at the dynamics between the waiting ovum and the sperms that swim towards it. The team says that there is a chemical communication that occurs between the female reproductive system that receives the sperm and the incoming sperm cells from the male partner. They explained that the primary mechanism might be known, but the molecular mechanism that forms the basis of choice of sperm cell by the egg is not clear. They write, "there is a growing appreciation that females can bias sperm use and paternity by exerting cryptic female choice for preferred males."

This is a fascinating area of research. There is much that is not as it historically seems.

Thank you for listening to my female biology-splaining.
